The init script(s) provided in FILESDIR for mail-filter/sid-milter has a license of GPL-2 but GPL-2 isn't within the LICENSE variable of the ebuild(s): files/sid-filter.init has license line: # Distributed under the terms of the GNU General Public License v2 ... and is used by the following ebuilds: sid-milter-1.0.0-r5.ebuild:LICENSE="Sendmail-Open-Source" There are two options here -- either LICENSE in the ebuilds should be appended with GPL-2 to cover the init script, or the init script should be relicensed so that it is covered by current LICENSE (this one is probably the preferred resolution). See also bug 425702 .
Package removed.
